Modified prone position using lateral brace attachments for cervico-dorsal spine surgeries.

PURPOSE

The purpose of the study was to propose a method of prone positioning for posterior cervico-dorsal spine surgeries that is easy to achieve without additional equipment and may reduce complications associated with prone positioning in patients.

METHODS

41 patients underwent posterior spine surgeries using our method of prone positioning on a fluoroscopy compatible conventional operation table, and the technical difficulties and complications associated were noted. After induction under general anaesthesia in supine position, cervical tongs were applied. An assembly of two adequately padded cylindrical bolsters and two lateral brace attachments was set on a conventional operating table. The patient was then positioned prone so that the tongs as well as insertion pins of the tongs rest on the lateral brace attachments, with the face and head suspended freely in between. A neutralisation weight was then applied suspended from the tongs to stabilize the head.

RESULTS

The time required for patient positioning was noted and was found to be nearly the same as that required for traditional prone positioning. No problems were noted during patient positioning and with anaesthesia tubing management. All surgeries went well without position related complications except for one patient who developed post-operative macroglossia. All cervical tong pin sites healed without any complications. The fluoroscope easily gained access to the operative areas.

CONCLUSIONS

Our modification appears simple, versatile and reproducible for posterior approach procedures of the cervical and upper dorsal spine in prone position. Also, the method can be easily implemented in most conventional operating room facilities with minimal surgeon effort and without the need for any additional inventory.
